A token filter of type stop that removes stop words from token
streams.

The following are settings that can be set for a stop token filter
type:

stopwords

A list of stop words to use. Defaults to _english_ stop words.

stopwords_path

A path (either relative to config location, or absolute) to a stopwords
file configuration. Each stop word should be in its own "line" (separated
by a line break). The file must be UTF-8 encoded.

ignore_case

Set to true to lower case all words first. Defaults to false.

remove_trailing

Set to false in order to not ignore the last term of a search if it is a
stop word. This is very useful for the completion suggester as a query
like green a can be extended to green apple even though you remove
stop words in general. Defaults to true.
